Learn Russian: Хорошая самооценка помогает найти стабильность в жизни. - Good self-esteem helps to find stability in life.

It is a compound word made of сам- (self) and оценка (evaluation, estimate, or grade). The -о- is a standard connecting vowel. You will see само- in many other Russian words corresponding to 'self-' or 'auto-', like самоуверенность (self-confidence) or самостоятельный (independent).

Why do we use the perfective verb найти right after the imperfective verb помогает?

The imperfective помогает is used because good self-esteem always or generally helps—it is an ongoing truth. However, the perfective найти is used because the ultimate goal of that help is a completed, successful result: actually finding stability.

The word стабильность looks like it's in the dictionary form. Why doesn't it take an accusative ending since it's the direct object of найти?

It actually is in the accusative case here! Стабильность is a feminine noun ending in a soft sign (-ь), which means it belongs to the 3rd declension. For inanimate 3rd declension nouns, the accusative form is identical to the nominative form.

In English we often say 'helps you find' or 'helps people find'. Why is there no dative pronoun after помогает?
